Only downside with Yubikeys is that you can’t really have backups. The solution is to have two of them, and add the 2FAs to each of them every time you sign up for a new account. It does mean you pretty much can’t have offsite backups though.
Personally I keep a USB-A with NFC one on my keyring and then a UISB-C one at my desk, which covers every device I have.
